3 Claims.

My invention relates generally to window screens, and particularly -to'a window screen having a frame in a window opening, and an important object of my invention is to provide a screen of the character'indicated wherein'the frame is adjustable to window openings of different height for permanent installation therein.

Another important object of my invention is to provide screen structure of the character indicated which involves a screen member which is arranged on a roller to be raised and lowered within the screen frame.

Another important'object of my invention is to provide inscreen structure of the character indicated, a frame which includes at its upper and lower ends, laterally outwardly expanding means for engaging the window opening to support and hold the frame permanently installed in the window opening.

Another important object of my invention is to provide screen structure of the character indicated which may be formed successfully of a variety of materials, and have sides and top and bottom members of different cross sections, the entire frame being of simple and inexpensive structure and arrangement, making quantity manufacture and distribution feasible.

Other important objects of my invention will be apparent from a reading of the following description taken in connection with the drawings, wherein for purposes of illustration I have shown a preferred embodiment of my invention.

In the drawings:-

Figure 1 is a general front or outer side elevational view of the embodiment showing portions thereof in longitudinal cross section.

Figure 2 is a transverse vertical sectional view taken through Figure 1 approximately on the line 2-2 and looking toward the right in the direction of the arrow.

Figure 3 is an elevational view of the inner side of the upper part of Figure 1.

Figure 4 is a horizontal sectional View taken through Figure 3 showing the operative position of the spring latch which holds the adjusted position of the movable screen element.

Figure 5 is a horizontal sectional view taken through the lower part of the screen element and showing the arrangement of the handle.

Figure 6 is a horizontal sectional view taken through Figure 1 approximately on the line 6-6 and looking downwardly in the direction of the arrows.

Figures 7 and 8 are views similar to Figure 6 of other formations of the sectional side members of the frame.

Referring in detail to the drawings, the numeral 5 generally designates the embodiment which comprises the tubular top cross member 6 having the cross section shown in Figure 2 and including the roller casing l in which is mounted the screen element roller 8 on which the screen element 9 is rolled in the manner of a window shade. The roller casing 7 includes the back plate It in the middle of which is arranged a horizontally disposed spring latch device 1 I which is anchored at one end as indicatedby the numeral I 2 and has its opposite end outwardly directed as indicated by the numeral l3 and disposed in an opening I 4 in the back plate ill for the purpose of engaging the screen element 9. The casing I has end closures l5 and I6;

Longitudinally disposed in the tubular member 6 above the casing 1 and slidably resting on a portion of the casing I are the upper window openings engaging expansion members I! and I8 corresponding in construction and operation to the expansion members i7 and I 8 at the lower end of frame 5 and which have at their inner endstoothed openings I9 with which is meshed a pinion the corresponding pinion 20 for operating expansion members I! and I8 is mounted in the back of the tubular member 6 and has an exposed wrench-grip portion 2i whereby the pinion 20 may be rotated to cause the members I? and [8 to move laterally inwardly or laterally outwardly and force window opening engaging members 22 and 23 through corresponding openings 24 and 25 into engagement with the window opening; in a manner to hold and lockthe embodiment in the window opening in which it is to be installed.

The frame 5 further comprises the lower horizontal tubular member 26 whose cross section is clearly shown in Figure 2 and which contains the expanding members I? and I8 and the mechanism described as contained in the cross member 6, in substantial duplicate for holding and locking the lower part of the screen frame in the window opening.

Fastened to and depending from the opposite ends of the upper cross member 6 and the casing 1 are the upper side members 27 and 28 of the sectional side members which are generally designated 29 and 3|], and these upper sectional side members 21 and 28 have the form shown in Figure 6, the cross section being substantially square or rectangular with a vertical opening 3| in the laterally inwardly facing side and with a channel 32 in the laterally outwardly facing side for accommodating a set screw 33 which is mounted in the corresponding lower side member sections 34 and 35 in a boss 36 which slides in the channel 32 and is located near the upper end of the members 34 and 35 as indicated in Figure 1. The purpose of the channel and the set screw is to lock the sections 28 and 35 and 21 and 34, respectively, in properly relatively extended positions, the upper sections 21 and 28 being telescoped in the lower sections 34 and 35, as clearly indicated in Figures 1 and 2.

The lower ends of the lower sections 34 and 35 are fastened to the opposite ends of the lower cross member 25.

The lower cross member 25 includes a vertically projecting channel portion 36 which rises above the top of the cross member 26 proper, as clearly shown in Figures 1 and 2, to form a stop for the screen 9 when the same is in the fully lowered position shown in Figure 2.

The screen 9 which is wound on the roller 8 has binding its lower end the U-shaped rigid member 31 which includes on its inward side the handle 38. The lateral edges of the screen itself and of the member 31 are disposed within the openings 3| of the side members of the frame and sufiiciently outwardly of the extremities of the.

said openings so as to slide within the opposed members of the said openings 3|; and yet be insufficiently engaged in the said openings to resist pulling out of the said openings upon the impingement on the screen element of a force which would tear or break the screen or any part thereof, were the side edge portions of the screen more securely tethered to the frame 5. It is to be noted in this connection that should one or both of the side edges of the screen become displaced from the side members 29 and 30, proper replacement of the side edges in the openings 31 may be achieved by completely rolling up the screen and then bringing the screen down again into position.

The projecting portion 36 of the lower cross member 26 has openings 39 therein to receive prongs 40 projecting from the side of the screen opposite the handle 38, whereby the screen may be locked in the fully pulled down position.

Figures '7 and 8 illustrate like Figure 6 cross sections and arrangements of diiferently formed relatively slidable upper and lower sections for the side members 29 and 30. It is to be observed that the compact and interfitting arrangements exemplified in all three of these arrangements of the side members provide for taking up as little of the space of the window opening as is practical, provide for the minimum wear of the sections, and leave the sections with the maximum strength, without the use of any large material.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in the materials, and in the structure and arrangement of the parts, within the spirit of the invention and the scope of the subjoined claims.
